Specification of Letters Patent.

Application filed June .16, 1905. Serial No. 265,484.

To all whom it may concern:

Be-it known that I, JOHN H. BELL, a citi-' zen of the United States, residing at Hadd'onfield,-inthe county of Camden and State of New Jersey, have invented certain new and useful Improvements in Flushing-Valves, of which the following is aspecification.

This invention relates to flushing-valves, and has for its object the securing of a sufficlent flow of waterfora perfect flushand the prevention of the water-hammer and the chattering of the valve by a retarding movement regulated'by a piston disposed in an lndepen ent chamber charged with .oil and distinct and separate from the water-valve chamber.

. By employing a separate and non-communicatin chamber for the retarding-piston I am enab ed to use oil for its operatlon, and thereby avoid the trouble from sediment, dirt, and foreign substances incident to the retarding means when located in the water chamber and operative bywater, while b using a lubricating fluid in a se arate retar ing-chamber the parts are a ways free to work, never become clogged, corroded, or

congealed, and the timing means when once adjusted is automatic and requires no fur- The invention is illustrated in the accompanyin drawings, in which similar characters of reference indicate similar parts throughout the views, and in which Figure 1 is a section as to most parts on line A, Fig. -2.' Fig. 2 is a side elevation. Fig. 3 is a side elevation opposite to Fig. 2.

Fig. '4 is a top view. Fig. 5 is a section on line C C, Fig. 1. Fig. 6 is a top view of the timing or regulating piston. Fig. 7 is a section on line D D, Fig. 6. Fig. 8 is a section on line E E, Fig. "6.

The infiowing-water pi e. 1 issecured to an inlet-chamber 2, screw-t eaded to a watervalve chamber 3, so that chamber 2 may be turned to receive pipe 1 from any direction. The water-valve comprises a top plate or disk 4 and a soft orleather disk 5 1n chamber 2 andmounted upon the top of-chamber 3, which are joined by a screw 6 to a lower part having an upper plate 7, guiding-Wings'S, freely fitting within chamber 3, and lugs 9, having a pin 10 to connect the valve to rod 11. \Vithin chamber 2 arewings -12 toguide disk 4 and so placed as not to obstruct the inflow through pi e 1. An opening is rovided at the top 0 chamber 2, through w 'ch the valve may be passed without breaking the pipe-joint, and it is closed by a screw-cap Rod 11 is secured by a pin 14 to a crank 15 onshaft 16, the shaft being set to'one side of the center line A, (see Fig.2) with pin 14 on line A when the water-valve is closed. This arrangement and positions insure an easy and quick opening of the valve and the positive closing. of the valve by the crank, as the crank never reaches dead-center or ultimate movement, and the chattering of the valve is prevented. An opening 17, through which the crank may be inserted or removed, is closed by a screw-cover 18,'and a deliverypipe 19 is secured'to the lower part of the chamber 3. Crank-shaft 16 has a bearing20 I and a packing-washer 21 to prevent any water, sediment, or dirt being carried from chamber 3 into the oil-chamber 22. A hearing 23 is provided for the outer end of shaft 16, beyond which the shaft has a tapered rectangular-shape 24, over which fits the hub of lever or handle 25, secured by screw 26. Within the oil-chamber on shaft 16 is a crank 27, set so as to equally divide its movement above and below the center of the shaft and having a set-screw 28 to secure its position and a pin 29. Between crank 27 and bearing 20 a spiral spring 30 is placed over shaft 16 to holdcrank 15 snugly against washer 21.

Attached to pin 29 is a rod 31, downwardly passing and carrying'apiston 32, to which the rod is secured by a pin 33. At one side of the pin there is a passage 34 through the passage 35 therefrom for the free passage of oil above the piston to phamber 22, while into passage 34 there is screwed an adjustingrod.36 which is the means to limit the flow of oil through passages 34 35 from the space in chamber 22 below the piston to the space above the piston to insure an adequate fiow of'water for flushing, as Well as to prevent a too sudden closing of the watervalve, which would produce a water-hammer. There is another passage 37 through the piston opposite passages 34 35, witha" valve 38 at t e'bottom of the iston, and through this passage 37 the oil as the water-valve opens and the piston movesup, and the passage is closed by valve 38 as the piston moves down, at which time the flow-is through passages 34 35, limited by the adjusting-rod 36 according to its posi- 22 has atop cover 39 and a bottom cover 40.
